[H] Making a T-Shirt

So I was sitting there in class, almost phasing out, until I realized my friend had volunteered me to be the liaison for ideas of a class T-Shirt. Just as an explanation, AP Calculus, every year, has a different T-Shirt, as a pride thing, I suppose. Also, despite me being the liaison, no one has any ideas...Anyways, due to my lack of creativity, I go to the a mind-numbing awesomeness and manpower of TL, I shall ask you for one request:T-Shirt ideas that fit the genre of AP Calculus. It can be witty, deep, self righteous, etc.

EDIT: If you have some idea in terms of an image (i.e. IIRC, last year was "Integrals, my Antiderivitive" with the antidrug advertising campaign as a design. Secondly, I have no problem hiding a TL emblem in there somewhere, haha.Back to the point, for the ideas, if you have an image, you can just describe it. We'll find a way to get it into print.

so sin x, cos x and e^x were getting ready for this massive party (or function, har har) one day. sin x and cos x were both pretty excited, but they noticed e^x seemed kind of down about the whole thing. they exchanged glances and on the way to the party did their best to try and cheer him up. it didn’t quite work, though, and once they got there they resolved to just go ahead and have fun. after a couple of hours, cos x spied e^x sitting alone in a corner. concerned for his friend, cos x signalled to sin x and they both moseyed up to e^x, taking a seat at either side.

“you should really get out there, you know,” said sin x. “there are loads of people at this party. go and talk to someone!”

“yeah,” added cos x. “make some friends!”

e^x looked up, glancing first one way then the other. “it doesn’t matter,” he said morosely. “even when i integrate, it doesn’t make a difference!”
